  • Publication number: 20240243084
    Abstract: A wafer level fan out semiconductor device and a manufacturing method thereof are provided. A first sealing part is formed on lateral surfaces of a semiconductor die. A plurality of redistribution layers are formed on surfaces of the semiconductor die and the first sealing part, and solder balls are attached to the redistribution layers. The solder balls are arrayed on the semiconductor die and the first sealing part. In addition, a second sealing part is formed on the semiconductor die, the first sealing part and lower portions of the solder balls. The solder balls are exposed to the outside through the second sealing part. Since the first sealing part and the second sealing part are formed of materials having thermal expansion coefficients which are the same as or similar to each other, warpage occurring to the wafer level fan out semiconductor device can be suppressed.

  • Publication number: 20240066144
    Abstract: Described herein are liposome-based nanocarriers that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The composition of the liposome-based nanocarriers may also be tuned to selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., livers. Also described herein are methods of imaging and mapping the bone marrow and/or other reticuloendothelial system organs using the described liposome-based nanocarriers. These methods provide high resolution non-invasive and quantitative imaging via PET, which offers advantages over conventional imaging/tracking methods. Furthermore, in certain embodiments, the liposome-based carriers are used to stabilize and deliver radioprotectant/free radical scavenger drugs to the bone marrow, thereby protecting the bone marrow from subsequent radiation exposure, thereby limiting the adverse impact of radiation exposure of the individual.

  • Publication number: 20220023450
    Abstract: Described herein are compositions comprising liposome-based nanocarriers and associated drugs that selectively target bone marrow, minimize tumor delivery, and maintain high drug concentrations in bone marrow when compared to conventional systemic delivery. The compositions also selectively target lymph nodes and other reticuloendothelial system organs (e.g., spleen, e.g., liver), while minimizing delivery to the tumor in order to deliver drugs that prevent bone marrow suppression (BMS) or aid recovery post exposure to radiation. There are a wide range of scenarios for which such radiation protection is useful, e.g., protection from radiation delivered as part of cancer therapy, radiation from weapons, radiation from materials at a nuclear power plant or nuclear waste site, natural radiation in outer space (e.g., for astronauts), and the like. The described compositions are stable for prolonged periods of time, in some cases over a year in a kit formulation.
